I visited the next ruin, #2, according to the DSS.

Colours are a bit off, as I had to find a way to increase the visibility of the structures. Interesting layout.
Though I somewhat feel like to really discover what this was all about, we would have to use archaeological scanners like ground radar and the like, prior to some careful excavation.
I have made my way over to #3, now and scouted around quite a bit, but I feel like this isn't the right structure, either.
Maybe I'm just missing a few details, as how to find those other structures. I have found the Codex Cores and the Artefact Spires, but the Data Core Access and those Pylons are nowhere to be seen.
I fear I won't make it back before the time limit runs out... About two days left.
